I began to work on a translation of Schaeffer's landmark treatise at McGill
in the late 80s, but, with other fish to fry at the time, I set it aside and
have never been able to return to it. Certainly no English translation
existed at the time. I would be thrilled (but surprised) to learn that an
English translation is now available.

Of related interest: Michel Chion also published a valuable little book
titled Guide des objets sonores, dedicated to Schaeffer, his mentor.

thank you for mentioning Pierre Schaeffer. I also use his ideas about
/sound objects/ and /reduced/ /listening/ in my courses both in music
psychology and music education. i would appreciate if you could send me
any information you have about Pierre Scheffer's Sound Objects. Thanks a
lot.
